Drive of a life time

you can play the game here : https://brandonv99.itch.io/drive-of-a-life-time.

This is not a full game just a prototype, still editing a lot of stuff to make it better and easy to play. Drive of a life time is a game that just meant to be played for fun. 

Controls are:

- arrow keys

- space to shoot.

What are some more improvements that I can add to my game to make better?
